The measure will be 122 cause all you have to do is subtract 180 from 58 and you will get your answer cause a supplementary angle is an obtuse so thats 180 so you would have to subtract then two amd you will get your answer !!

Answer:
6
Step-by-step explanation:
Deisha's build rate = 1 fence per 15 hours = 1/15 fences per hour
Travis's build rate = 1 fence per 12 hours = 1/12 fences per hour
Working together, their combined rate is 1/15 + 1/12 = 3/20 fences per hour
So it takes them 20/3 = 6 2/3 hours per fence
Answer:
-7/3 =x
Step-by-step explanation:
5x-15 = 8x-8
Subtract 5x from each side
5x-5x-15 = 8x-5x-8
-15 = 3x-8
Add 8 to each side
-15+8 = 3x-8+8
-7 = 3x
Divide each side 3
-7/3 = 3x/3
-7/3 =x
